And by the way, thanks for ruining "Carnival" for me, people. At least that saves me some time, I suppose.

Jacob not being a real person is the best thing that could happen, but I'm just trying to fit a J person into the coffin. And the other alternatives would be even worse than having Jacob turn out to be a real dude. I guess it could've been Sawyer or Locke under an assumed name, or for that matter, any of the male castaways.
